EchoSwitch LU74-78 Ultrasonic Level Switch

The general purpose ultrasonic level sensor provides continuous level detection up to 26.2’ (8m) with 3 programmable relays for level switch or level control functions, and a 4-20mA signal output.

EchoSwitch II features digital push button configuration, eliminating target calibration. Each relay can be configured on a single set point to control pumps, valves or alarms. In addition, all 3 relays can be simplexed, duplexed or triplexed.​EchoSwitch II now features an integrated timer with pump/valve delay and timed pump alternation. The switch is well suited for a broad range of corrosive, waste and slurry type media and is broadly selected for atmospheric day tanks, pump lift stations and waste sump applications.

Features of the EchoSwitch LU7 Ultrasonic Level Switch include:

Simple digital push configuration, no more target calibration

Available in 2.5m or 7.5m range

10cm miniature dead band optimises the filling capacity of sumps or vessels
